What is the difference between a backup system, an Energy Storage System and an Off-grid system?
A backup system powers the critical loads for the duration of the expected downtime. An Energy Storage System powers the base load with solar during the day and stores excess solar energy to power through the evening and night enabling self-consumption, the grid assists in powering peak consumers or on grey days. An off-grid system powers all loads 24/7 based on worst case scenarios as there is no reliance on a grid. It is possible to start with a backup system and become more and more self-sufficient.
How to power remote populations with micro- and nanogrids
Our off-grid products provide attractive business opportunities for Energy Access. From the smallest systems to powering communities or even entire villages: with Victron Energy you can power it all. See how unequalled reliability converts into secure investments.

How to achieve peace of mind in off-grid.

Thanks to the feedback loop we have with our partners and clients and decades of mastering power challenges with innovation, our off-grid know-how and capability means we can promise Energy. Anytime. Anywhere.


It’s not one thing that makes it all work.

Our modular, robust and connected off-grid systems have been proven to deliver unequalled reliability time and time again, even in the harshest of climates. It’s our unique combination of up-to-date hardware and software, intelligent monitoring Apps, our network of highly trained Authorised professionals and widespread repair centres that makes Victron systems unbeatable systems.


Bad power.
Great load protection.

Generators or even the grid in some regions may provide bad quality power: voltage drops, or frequency shifts can negatively impact the lifespan of your appliances and thus your investments. Victron’s extremely resilient inverter/chargers protect your loads like a vault, monitoring the incoming power on all parameters. Our Professional duty inverters safely power sensitive electronics thanks to the pure Sine Wave. They come with a very high peak power performance so heavy machines and variable loads can be powered problem free.


Intelligent monitoring means optimised systems

Monitoring is crucial to fine tune and optimise energy harvest and use based on ever changing circumstances. With Victron you can experience the power of know-how right from your hand. Through our industry leading and free VictronConnect app, you always have perfect control over your system from wherever you are. With our App and VRM portal you can monitor the complete system, change settings and catch potential issues early by programming alerts and alarms.


Build it right.
Configure. Scale.

Victron’s off-grid abilities are simply unmatched, which gives our customers the ability to build, configure and scale a backup, ESS, or off-grid systems exactly to their wishes. From the smallest hut to the largest resorts, our off-grid systems start from 500W and can virtually provide unlimited power through parallel operation. Three or split phase operations are also possible. Our modular setup means you could start small and scale later to stay on par with rising power demands.


Open architecture
means choice.

We believe that offering choice to our customers is crucial. Great efforts are made to ensure a deep and problem free integration with a long list of third party managed battery brands, AC-PV manufacturers and more. Managed batteries can be integrated through our GX devices in minutes. AC-PV inverters are supported directly after installing a software assistant on our inverters. We are proud to closely work together with many of the leading brands. The global recognition for our efforts only pushes us further, giving ‘seamless’ even more meaning.


means local expertise

Every off-grid system is different and different locations present unique challenges. That is why Authorised Victron Professionals are trained with the highest level of know-how. Their local expertise is also vital. All the variables need to be considered with regard to the local climate and local costs of solar panels, battery banks, etc. This is why designing an off-grid system is a local Authorised Victron Installers job. If repairs are required, our worldwide repair network covers even the most remote areas with a quick service.
